Certainly a question which has been asked one billion times. If so, sorry about that:
Is it safe to disable or delete SwissKnife once the design job is done?
I’ll explain myself. I use a plugin backup which returns errors when the backup job is scheduled.
The support guys say that it could be one or more plugins which slow and abort the backup job. So, I search the faulty one (could be SwissKnife or not).
